ing, falling, or both depending on CTR1 D5; D4) is detected, T16 captures HI16
and LO16, reloads, and begins counting.
If D6 of CTR2 Is 0
When a subsequent edge (rising, falling, or both depending on CTR1, D5; D4) is
detected during counting, the current count in T16 is complemented and put into
HI16 and LO16. When data is captured, one of the edge detect status bits (CTR1,
D1; D0) is set, and an interrupt is generated if enabled (CTR2, D2). T16 is loaded
with

Do not load these registers at the time the values are to be
loaded into the counter/timer to ensure known operation.
An initial count of 1 is not allowed. An initial count of 0
causes T16 to count from 0 to
from 0 to
and starts again.
